I've been thinking lately: If I fasted for about 20 hours and then drank a liter of olive oil, what would happen?

Stomach problems aside, you'd have no/little insulin in your blood stream from the fast plus there'd be no insulin spike from the oil. The calories would go to feed you but you'd theoretically gain no fat correct?

This makes me think about fasting for about 18h, putting down a bunch of olive oil, protein(eggs, chicken, tuna), coffee, no carbs and going for a strength session...finish the session off with some carbs and protein and no fat...
